The Carnegie-Irvine Galaxy Survey. III. The Three-Component Structure of Nearby Elliptical Galaxies
Song Huang, Luis C. Ho, Chien Y. Peng +2
Motivated by recent developments in our understanding of the formation and evolution of massive galaxies, we explore the detailed photometric structure of a representative sample o…
Subhaloes gone Notts: Spin across subhaloes and finders
Julian Onions, Yago Ascasibar, Peter Behroozi +15
We present a study of a comparison of spin distributions of subhaloes found associated with a host halo. The subhaloes are found within two cosmological simulation families of Milk…
Exploring the Cosmic Reionization Epoch in Frequency Space: An Improved Approach to Remove the Foreground in 21 cm Tomography
Jingying Wang, Haiguang Xu, Tao An +7
Aiming to correctly restore the redshifted 21 cm signals emitted by the neutral hydrogen during the cosmic reionization processes, we re-examine the separation approaches based on…
Kinematics of the Compact Symmetric Object OQ 208 revisited
Fang Wu, Tao An, Willem A. Baan +6
Aims. A long timeline kinematic study of the archetypal CSO OQ 208 sheds light on the physical properties of the most compact radio sources. Methods. Archival data from the VLBA at…
Stellar mass versus stellar velocity dispersion: which is better for linking galaxies to their dark matter halos?
Cheng Li, Lixin Wang, Y. P. Jing
It was recently suggested that, compared to its stellar mass (M*), the central stellar velocity dispersion (sigma*) of a galaxy might be a better indicator for its host dark matter…
The Dynamic Evolution of Young Extragalactic Radio Sources
Tao An, Willem A. Baan
The evolution of symmetric extragalactic radio sources can be characterized by four distinct growth stages of the radio luminosity versus size of the source. The interaction of the…
The Baldwin effect in the narrow emission lines of AGNs
Kai Zhang, Ting-Gui Wang, C. Martin Gaskell +1
The anti-correlations between the equivalent widths of emission lines and the continuum luminosity in AGNs, known as the Baldwin effect are well established for broad lines, but ar…
Galaxies going MAD: The Galaxy-Finder Comparison Project
Alexander Knebe, Noam I. Libeskind, Frazer Pearce +8
With the ever increasing size and complexity of fully self-consistent simulations of galaxy formation within the framework of the cosmic web, the demands upon object finders for th…
Constraining the substructure of dark matter haloes with galaxy-galaxy lensing
Ran Li, Houjun Mo, Zuhui Fan +2
With galaxy groups constructed from the Sloan Digital Sky Survey (SDSS), we analyze the expected galaxy-galaxy lensing signals around satellite galaxies residing in different host…
The distribution of faint satellites around central galaxies in the CFHT Legacy Survey
Chunyan Jiang, Yipeng Jing, Cheng Li
We investigate the radial number density profile and the abundance distribution of faint satellites around central galaxies in the low redshift universe using the CFHT Legacy Surve…
What governs the bulk velocity of the jet components in active galactic nuclei?
Bo Chai, Xinwu Cao, Minfeng Gu
We use a sample of radio-loud active galactic nuclei (AGNs) with measured black hole masses to explore the jet formation mechanisms in these sources. Based on the Königl's inhomoge…
A Re-examination of Galactic Conformity and a Comparison with Semi-analytic Models of Galaxy Formation
Guinevere Kauffmann, Cheng Li, Wei Zhang +1
The observed correlation between star-formation in central galaxies and in their neighbours (a phenomenon dubbed galactic conformity) is in need of a convincing physical explanatio…
Anomalous anisotropic cross-correlations between WMAP CMB maps and SDSS galaxy distribution and implications on the dark flow scenario
Zhigang Li, Pengjie Zhang, Xuelei Chen
We search for the dark flow induced diffuse kinetic Sunyaev Zel'dovich (kSZ) effect through CMB-galaxy cross correlation. Such angular correlation is anisotropic, with a unique $co…
ALFALFA HI Data Stacking III. Comparison of environmental trends in HI gas mass fraction and specific star formation rate
Silvia Fabello, Guinevere Kauffmann, Barbara Catinella +3
It is well known that both the star formation rate and the cold gas content of a galaxy depend on the local density out to distances of a few Megaparsecs. In this paper, we compare…
Satellites and Haloes of Dwarf Galaxies
Laura V. Sales, Wenting Wang, Simon D. M. White +1
We study the abundance of satellite galaxies as a function of primary stellar mass using the SDSS/DR7 spectroscopic catalogue. In contrast with previous studies, which focussed mai…
The Evolution and Star Formation History of M33
Xiaoyu Kang, Ruixiang Chang, Jun Yin +4
We construct a parameterized model to explore the main properties of the star formation history of M33. We assume that the disk originates and grows by the primordial gas infall an…
Cosmological Constraints from a Combination of Galaxy Clustering and Lensing -- III. Application to SDSS Data
Marcello Cacciato, Frank C. van den Bosch, Surhud More +2
We simultaneously constrain cosmology and galaxy bias using measurements of galaxy abundances, galaxy clustering and galaxy-galaxy lensing taken from the Sloan Digital Sky Survey.…
Constraining Extended Gamma-ray Emission from Galaxy Clusters
Jiaxin Han, Carlos S. Frenk, Vincent R. Eke +5
Cold dark matter models predict the existence of a large number of substructures within dark matter halos. If the cold dark matter consists of weakly interacting massive particles,…
Bulk flow of halos in ΛCDM simulation
Ming Li, Jun Pan, Liang Gao +10
Analysis of the Pangu N-body simulation validates that the bulk flow of halos follows a Maxwellian distribution which variance is consistent with the prediction of the linear theor…
Peculiar Velocity Decomposition, Redshift Space Distortion and Velocity Reconstruction in Redshift Surveys - I. The Methodology
Pengjie Zhang, Jun Pan, Yi Zheng
Massive spectroscopic surveys will measure the redshift space distortion (RSD) induced by galaxy peculiar velocity to unprecedented accuracy. We develop a new method to improve the…
Cosmological Constraints from a Combination of Galaxy Clustering & Lensing -- II. Fisher Matrix Analysis
Surhud More, Frank van den Bosch, Marcello Cacciato +3
We quantify the accuracy with which the cosmological parameters characterizing the energy density of matter (Ω_m), the amplitude of the power spectrum of matter fluctuations (σ_8),…
Cosmological Constraints from a Combination of Galaxy Clustering and Lensing -- I. Theoretical Framework
Frank van den Bosch, Surhud More, Marcello Cacciato +2
We present a new method that simultaneously solves for cosmology and galaxy bias on non-linear scales. The method uses the halo model to analytically describe the (non-linear) matt…
